Accurate identification of aquatic organisms and their numerical abundance calculation using echo detection techniques remains a great challenge for marine researchers. A software architecture for echo data processing is presented in this article. Within it, it is discussed how to obtain energetic, morphometric and bathymetric fish school descriptors to accurately identify different fish-species. To accomplish this task it was necessary to have a development platform that allowed reading echo data from a particular echosounder, to detect fish aggregations and then to calculate fish school descriptors that would be used for fish-species identification, in an automatic way. This article also describes thoroughly the digital processing algorithms for this automatic detection and classification, as well as the automatic process required for surface and bottom line detection, which is necessary to determine the exploration range. These algorithms are implemented within the ECOPAMPA software, which is the first Argentinean system for marine species identification. Finally, a comparative result over experimental data of ECOPAMPA against Echoview TM Software Pty Ltd (formerly Myriax Software Pty Ltd), is carefully examined.Postharvest diseases and disorders are two of the most important parameters associated with the quality of avocado fruit. The aim of this study was to identify postharvest diseases and disorders in Hass avocado plots and to evaluate their relationships with different preharvest agronomical practices. This work was developed in 20 commercial plots of Hass avocado dedicated to production for national and export markets. The first part of this work was associated with the identification and characterization of diseases and disorders related with postharvest of avocado. In addition, it was determined the incidence of each disease and disorder based on simulation of postharvest scenarios for the national and export markets. Using a multinomial logistic regression model, it was possible to determine that the presence of each disease and disorder were related to crop management practices, soil and leaf and fruit nutrients levels. Most relevant postharvest disease and disorders were anthracnose, stem-end rot, chilling injury, and lenticel damage. Additionally, variables such as dry matter, plant pruning, and tissue concentration of Ca+2 were related with some pathologies and disorders. This work presents an advance in the recognition of postharvest diseases and disorders in avocado under tropical conditions, besides determining the main edaphic and anthropogenic associated factors.We aim to estimate and compare the costs of operative and transcatheter closure for patients with secundum atrial septal defect (ASD) in Vietnam. This was a retrospective cross-sectional study based on medical records of congenital heart diseases (CHD) patients in Da Nang Hospital, Vietnam from 2010 through 2015. All costs in this study were calculated according to a provider's perspective. All pricing data were converted into USD at the 2015 exchange rate. A total of 258 patients with secundum ASD were recruited in the study, including 35 patients treated by operative closure and 223 patients treated by transcatheter closure. The total treatment costs of the transcatheter closure group (US $3,107.9) were higher than those of the operative closure group (US $2,080.5). The cost of the procedure and medical supplies accounted for 67.3% of the total treatment cost in the operative closure group, while the cost of occlusion devices accounted for 62.2% of the total cost in the transcatheter closure group. Given the advantages of the transcatheter closure procedure, reducing occlusion device costs may increase the proportion of patients treated with this technique.It has been well documented that administration of melatonin could reveal antidepressant-like effect in rodents. However, the protective effect of melatonin on stress-induced depression/anxiety and its underlying mechanism is yet to be understood. In this regard, in the current study, acute foot-shock stress (FSS) was used to evaluate the antidepressant-like effect of melatonin on neurogenic stress-induced depression in mice. Behavioral evaluation was done by using the forced swimming test (FST) and Open-field test (OFT). Melatonin, MK-801, and ketamine (NMDA receptor antagonists), and NMDA (NMDA receptor agonist) were used to elucidate any association between melatonin and NMDA pathway in behavioral despair induced by acute-FSS. Applying acute-FSS to mice significantly induced depressant-like behavior in FST without any significant impact on locomotor activity in the OFT. We observed that melatonin (dose-dependently) significantly improved the depressant-like effect of FSS, but it did not impact the locomotion in animals. https://www.selleckchem.com/products/sulfatinib.html Acute injection of MK-801 at sub-effective doses (0.01 mg/kg) or ketamine (0.1 mg/kg) potentiated the antidepressant-like effect of a sub-effective dose of melatonin. However, the sub-effective dose of NMDA (30 mg/kg) abolished the protective effect of melatonin on the behavioral profile of stressed animals. Our results could reflect the antidepressant-like effect of melatonin on neurogenic stress-induced depressive behaviors in mice. Also, our results showed that NMDA receptors could be involved in the antidepressant-like effect of melatonin.Here we report 3 cases of neuromyelitis optica spectrum disorder (NMOSD), who were all treated with eculizumab and could be observed with monitoring serum C3, C4 and 50% hemolytic complement (CH50) before and after the treatment. Serum C3 and C4 were not dramatically changed during the treatment, in contrast serum CH50 level of each patient had diminished and kept under the detection limit after the treatment without clinical worsening, even in the situation of extending dosing. Serum CH50 level is useful to monitor the drug efficacy during eculizumab treatment.Vermi-composting is an environmental friendly and economic process to decompose organic waste. The objective of this study was to produce vermi-compost using Eiseniafetida and to investigate the impact of vermi-compost (VC) and organic manure (cow dung) on seed germination, seedlings, and growth parameters of Tagetes erecta. Physio-chemical parameters of vermi-compost and organic manure were recorded. A potting experiment was designed, germination medium containing soil, sand, and various concentrations of vermi-composts. The composition of germinating media was TO (Sand + Soil), TCC (Sand + Soil + Cow dung), 10% VC (Sand + Soil + 0.1 kg VC), 15% VC (Sand + Soil + 0.15 kg VC), 20% VC (Sand + Soil + 0.2 kg VC), 25% VC (Sand + Soil + 0.25 kg VC), 30% VC (Sand + Soil + 0.3 kg VC), and 35% VC (Sand + Soil + 0.35 kg VC). Seed germination, seedling, vegetative plant growth, and flowering parameters were evaluated in different germinating media. Pre and post-physio-chemical parameters of germination media were also recorded to check their stability and quality.
